UNITED STATES PATENT OFFICE.

ARTHUR R. HAVENER, 0F WALTHAM, MASSACHUSETTS, ASSIGNOR TO AMERICAN LACINCT HOK C0., A CORPORATION OF NEW JERSEY.

To all whom it may concern Be it known that I, ARTHUR R. Havanna', a citizen of the United States, residing at Vilaltham, in the county of Middlesex and State of Massachusetts, have invented new and useful. lmprovements in LacingHook- Setting Machines, of which the following is a specification.

This invention relates to machines for setting articles such as lacing hooks, eyelets and the like in sheet material and is particularly adapted to set lacing hooks inthe uppers of boots and shoes.

The invention is an improvement upon the machine invented by Arthur R. Havener and patented November 29,1910,No.977,090.

In machines of the class set forth the lacing hooks are liable to become jammed or not to feed freely along the raceway and onto the lacing hook carrier and are also liable to be caught upon the lacing hook carrier when said carrier is being withdrawn from said lacing hook.

One of the principal objects of an automatic machine for setting lacing hooks such as that shown and described in said Havener patent and also in this application is to set the lacing hooks in the upper of the boot or shoe and feed the upper very rapidly. Any delay which may be caused by a lacing hook becoming jammed or not feeding properly from the time it passes down the race way until it is set in the upper of a boot or shoe lessons the efficiency of the machine.

lt is the object of this invention to provide a machine of the class set forth in which the parts are so constructed and arn ranged that if a lacinghook becomes jammed anywhere from the lower part of the race way to the anvil and punch upon which it is set, it can be easily and quickly removed by the operator with very slight delay in the ruiming of the machine.

To these ends the invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

`Referring to the drawings: Figure 1 is a front elevation of my improved lacing hook setting machine partly broken away to save space in the drawings. Fig. 2 is a side ele vation of the same as viewed from the right of Fig. 1, the hopper being broken away.

Specification of Letters Patent.

Application led November 215, 1912.

Patented Julie 2, 1914s.

Serial No. 733,254.

Fig. 3 is a sectional elevation taken on the irregular line 3--3 of Fig. 1. Fig. 4 is a plan view of the work-support, presser foot and setting instrumentalities, a part of the work-support being shown thrown back in dotted lines, parts being shown broken away and a portion of the frame being shown in section. Fig. 5 is a detail sectional elevation taken on line 5 5 of Fig. 4.-. Fig. 6 is a detail sectional elevation taken on line 6 6 of Fig. 4. Fig. 7 is a detail plan of the two parts of the work-support with the lacing hook carrier and a portion of the raceway shown in connection therewith. Fig. 8 is a detail sectional elevation taken on line 8 8 of Fig. 2. Fig. 9 is a detail section taken on line 9 9 of Fig. 3.

Like numerals refer to like parts throughout the several. views of the drawings.

In the drawings, 10 is the frame; 11 is the main driving shaft j ournaled in bearings 12 in said frame and driven by a suitable clutch pulley 13. A pulley 14C is fast to the pulley 1S and is connected by a belt 15 to a pulley 1G fast to a shaft 17 to which is fastened a worm 18 which meshes into and rotates a worm gear 19. The worm gear 19 is fast to a shaft 20 which rotates in suitable bearings and has fastened thereto the rotatable member of the lacing hook hopper 21. This hopper is constructed in a manner well known to those skilled in the art and has a raceway 22 leading out of the same and downwardlyto meet an auxiliary raceway 23 (Fig. 3).

The lacing hooks are fed from the main raceway down the auxiliary raceway 23 one by one by means of a detent 211 pivoted at 25 to the frame of the machine. This detent has an arm 20 which bears against the rear edge of a feed lever 27 pivoted at 28 to the frame of the machine. A spring 29 and link 30 hold the arm 26 of the detent 241 in yielding engagement with the rear edge of said feed lever Q7.

The link 30 extends through a slot 31 in the frame 10 and has a cross-pin 32 fast thereto and bearing against the rear face of said frame. The upper end of the lever 27 projects between the two sides of the auxiliary raceway 23 and has a rocking movemeut imparted thereto by a link 38, cam lever 34 and cam 35. The cam is fastened to the shaft 11. The lever 31 is pivoted at 36 to the framejof the machine vand is connected to the link 33 by a pin 38 which has a handle 39 fast thereto and projecting laterally from the lever 34 through an opening hooks which may be located thereon or leav-I ing the same open so that any lacing hook which may have become iammed upon said auxiliary raceway may be pushed downvardly and olf of said raceway.

T he lacing hooks are fed one by one from the detent 24 down the auxiliary raceway 23 and are pushed by the upper end of the feed lever 27 onto a carrier lever 4l which is pivoted at 42 to a slide 43. A vertical movement is given to the/slide 43 and the carrier lever 4l by a rocker arm 44 pivoted to a stud 45. A rocking movement is impartedto the arm 44 by a cam 46 fast to the rock-shaft 47. A rocking movement is imparted to the carrier lever 4l to remove the same from the'lacing hook, after the lacing hook has been set in the upper, by a slide 48 which is connected by a pin 49 to the lower end of the carrier lever 4l and is operated by a pin 50 fast to the lever 27 and projecting into a slot 5l provided in said slide 48. A spring is connected at one end to said slide 48 and at the other end to said lever 27.

Then the lever 27 is moved toward the left (Fig. 3) and the pin 50 abuts against the left hand end of the slot 5l, the slide 48 will be moved to rock the lever 4l and withdraw the same from the lacing hook. lllhen said lever moves in the opposite direction, the spring 52 will move the slide 48 toward the right, tipping the lever 41 upon its pivot 42 and moving the upper end of said lever toward the left in position to receive a lacing hook from the lower end of the auxiliary raceway 23 and in the position illustrated in Fig. 3.

The link 33 is made in two parts 53 and 54, the part 53 having a cylindrical shank 55 thereon which projects into a corresponding hole in the part 54 and is clamped by screws 56 to the part 54, as particularly illustrated in Fig. 9. Thus the length of the link 33 can be increased or diminished and the relative location of the upper end of the lever 27 and consequently of the detent 24 which bears against the rear edge of said lever can be adjusted.

The work-support 57 for the upper is made in two parts, a stationary part 58 and a movable part 59. Between the adjacent edges of these two parts 58 and 59 of said work-support 57 are located the lacing Vhook carrier lever 4l and the auxiliary raceway 23. rlhe front corner 60 of the stationary vpart 58 is bent downwardly toassist in guiding the upper into position when it is rst inserted in the machine.

The part 59 is mounted on a pivotal pin 61 (Figs. l, 4 and 5)`between two ears 62 and 63 forming a part of the frame l0 and is locked in operative position by a slidahle pin 64 which slides in the ear 63 and is held in locking engagement with the movable part- 59 by a spring 65 which normally holds said pin 64 in the position illustrated in Fig. 5, the upper end of said pin projecting into a hole 66 in the part In order to throw the pin 64 downwardly out of locking engagement with the part 59, a lever 67 is provided which is pivoted at 68 to the frame and is adapted to engage a cross-pin 69 on the pin 64, said cross-pin projecting through a slot 70 provided in the ear 63.

The movable part 59 is shown in full lines in Figs. 4 and 7 and is also shown in dotted lines (Fig. 4) in the position which it occupies when thrown out of operative position for the purpose of enabling the operator to get at the auxiliary raceway and the carrier lever to remove any lacing hook which may have become jammed or stuck.

The movable part 59, it will be seen, has twoarms 7l and 72 separated from each other by a passageway or slot 73, which, when said movable part is in position, ez;- tends laterally of the punch and provides a passageway for the lacing hook which has been set in the upper, during the feeding movement of the upper.

The arm 7l has a raised portion 74 at its outer end against which bears the under side of one leg of the U-shaped presser foot 76. The arm 72 has a raised portion 7 7 against which the other leg 78 of said U- .shaped presser foot is adapted to bear. Said presser foot has a rearwardly extending arm 79 which is fastened to a vertical shaft 8O adapted to slide in bearings 8l, 82 in the frame lO. Said -presser foot is held down upon the movable port-ion of the work-support or against the upper on said work-Support by a spring 83 which encircles the vertical shaft 80, bearing at its upper end against the lower side of the bearing 8l and at its lower end against an arm 84 fast to the shaft 8O and guided at its free end by a plate 85 fast to the frame of the machine.

,T he presser foot is raised and lowered automatically by a lever 86 which is pivoted at 87 to the frame of the machine, and has a rocking movement imparted thereto by a. cam 88 fast to the shaft ll (see Fig. l). ll`he presser foot shaft 8O is adapted to be engaged at its lower end by a'lever 89 which is pivoted at 90 to the frame of the machine and is connected by a link 91 to another lever 92 fast to a rock-Shaft 93 journaled to rock in the frame of the machine and manually operated by a treadle rod 94 connected to a suitable treadle (not shown in the `draw-` ings) The rock-shaft 93 has an arm 95 fast thereto adapted to engage a pin 96 in the slide 97. Said slide is adapted to operate the clutch 98 and thus lock the pulley 13 to the shaft 11 in a manner well known to those skilled in this art. lVhen the treadle is de pressed the rod 94 is moved downwardly, t-hus rocking the lever 92 and moving the slide 97 toward the left (Fig. 2) to allow the clutch to lock the pulley 13 to the shaft 11. At the same time, through the link 91, the lever 89 allows the rod 80 and the presser foot to drop downwardly, so that said presser foot can press the work against the work-support and said presser foot is thereafter automatically raised and lowered by the cam 88 during the feeding of the upper.

The upper is fed in substantially the same manner as described in said patent, viz., by a punch 99, said punch having an anvil 100 thereon against which the lacing hook is clenched in the manner described in said Letters Patent. The punch and anvil are fastened to a slide 101 and this slide is guided to impart a lateral movement to the punch upon tubular rods 102 fast to a plunger 103. The slide 101 is moved upon the rods 102, in order to give the punch its feeding movement, by an arm10ll fast to a rockshaft 105 mounted in bearings 106, 107 in the frame and a rocking movement is imparted to said rock-shaft by an arm 108 con nected by a link 109 to a lever 110, said lever being operated to rock the same by a cam 111 fast to the shaft 11. The free end of the arm 104 has a stud 112 fast thereto which projects into a slide block 113 located in a slot 114: in the slide 101. Through this meehanism horizontal sliding movement is imparted to the slide 101 and to the punch fast thereto.

A vertical movement is imparted to the plunger 103 and therefore to the slide 101 and to the punch fast thereto by a rockerarm 115 fast to a rock-shaft 116 to which a rocking movement is imparted by an arm 117 connected by a link 118 to a lever 119. Said lever 119 has a rocking motion iinparted thereto by a cam 120 fast to the shaft 11. The free end of the arm 115 has a pin 121 fast thereto and projecting into a sliding block 122 adapted to move in a segmental slot 123 in a block 124 which is fastened to the plunger 103, and by this mechanism a vertical movement is imparted to the plunger 103 and to the slide 101 and punch fastthereto.

A gage 125 is provided for positioning the edge of the upper relatively to the punch and lacing hook carrier and this gage has a shank 126 thereon which projects through an ear 127 on the arm 72 of the movable part 59 of the work-support. This .gage is held in position by a set-screw 128. A gage 129 is also provided for positioning the upper longitudinally thereof, in order to determine the point at which the lirst. lacing hook shall be set therein. This gage 129 is slotted at 130 and through this slot projects a set-screw 131 having screw-threaded ongagement with the leg 78 of the U-shaped portion of the presser foot.

A spring 132 is interposed between t-he head of the screw 131 and the upper face of the gage 129. A guide pin 133 is fastened to the gage 129 and projects into a slot 134; in the upper face of the leg 78. The gage 129 is turned upwardly at 135 to provide a convenient means whereby said gage can be moved longitudinally thereof to set it in different positions relatively to the punch. Said gage is provided with a pointer 13G which extends downwardly over the inner edge of the leg 78 into close proximity with the upper which is located thercbeneath.

The general operation of the mechanism hereinbefore specifically described is as follows: The presser foot is raised from the work-support 57 by releasing the treadle and allowing the rod 9a to be moved upwardly by the treadle spring, which is not shown in the drawings. rlhis will rock the lever 92 and, through the link 91, the lever 89 will contact with the lower end of the presser foot shaft lifting the same, together with the presser foot, so as to allow the operator to insert the upper 137 beneath said presser foot and upon the upper surface of the work-support. 1n placing this upper in position the operator is assisted by the downwardly turned front corner 00 of the part 58 of the work-support. He pushes the upper along the upper face of the worlesupport until the front edge of the upper abuts against the edge gage 125, with the pointer 130 of the gage 129 alining with a suitable mark upon the upper of the shoe so that the first lacing' hook will be located properly therein. The operator then depresses the treadle and by so doing throws the clutch into operation and leaves the presser foot shaft free to bc operated by the lever 80.

A lacing hook is fed from the hopper 21 down the main raceway 22 onto the projection 138 on the detent 24rand when said detent is rocked by the lever 27 moving rearwardly said lacing hook will be dropped onto the auxiliary raceway 23 and will move down said raceway toward the lower end thereof, and upon the return movement of the lever 27 will be forced by the upper end of said lever onto the carrier lever 41. Said carrier lever will be carried upwardly by the slide 43 actuated by the arm 4141 and cam 46 which will drive the stem of the lacing hook through the upper 137 onto the lower end of the punch and against the anvil 100 whereby the shank of the lacing hook will horizontal movement imparted thereto by the mechanism hereinbefore described all in' the proper time so that said punch will descend, punch a hole in the upper and receive. the lacing hook as it is set thereon by the, lacing hook carrier, said punch then beingl moved laterally to feed the upper and after feeding the same the punch will rise and retreat to its former position ready to repeat the operation of punching, clenehing and feeding. 1f, during any of these movements, a lacing hook becomes jammed or does not feed freely along the auxiliary raceway or from said auxiliary raceway onto the carrier lever eil, or, if there is any ditliculty in removing the lacing hook from the lever 41 prior to the feeding movement of the upper by the punch, or, if in any of these various movements the lacing hook is not free to feed, the parts may be readily reached by swinging the movahle part 59 of the work-support from the position shown in full lines 4 and 7) to that shown in broken and do ted lines in Fig. a, this being accomplished hy rocking the lever G7 so as to'move the pin G4 downwardly out of the hole G6 in the part lv9 and then swinging the said part 59 into the position illustrated in broken and dotted lines, i.

The presser foot is held in a raised position bv means of the treadle rod 9i, levers 92 and 89 and the link 91 which cooperate to raise the rod 8O and the presser foot attached thereto. rlhus the raeeway and lac` ing hook carrier will be open to the manipulations of the operator to remove therefrom any hook which has become jammed or stuck upon any of the parts referred to.

The operator is further assisted in clearing the machine of any objectionable lacing hoch by the handle 3S) which enables him to rock the lever 84 backwardly and f rwardly and thus, through the link 38, to rock the lever 27 and the detent 24e to clear the auxiliary raceway or the projection 13S on the detent, or thD upper end of the lever 27 from any lacing hook which may have become caught on the raceway.

By loosening the clamp-screws 5G the part 53 may be slid in one direction or the opposite in the part and thus the position of the lever 27 and of the detent may be changed as desired and when said parts are in the desired position relatively to the lacing hook carrier lever li1 or the raceways and Q3, the clamp screws 56 may be tightened.
